To'aZZ whom it may concern:

Be it known that I, BONAPART SoHU'rz, a citizen of the United States,residing at Hillview, in the county of Greene and State of Illinois,have invented eertai'n'ne and useful Improvements in Car Doors; and :Ido hereby declare the following to 'be a'- ft1l'l, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it "appertai'ns to niakean'd usethe same.

The present invention relates to freight car doors, and more especiallyto suchdoor's of cars intended for grain, sandend 'simflar niaterials Ip r p v V It is the object ofthe invention to provide a doorconstrnction to be disposed with in the door opening of the car for"retaining the grain, sand ors'imilar material, w'ithont the necessityof nailing board's across the door opening as c'u'stornary, therebysaving expense and troubleas well as damage t'o'the door frame, andproviding for the convenient positioning'o'f the door in the opening andthe discharge of the material.

Another object is to provide novel'lnea'ns for mounting the door wherebythe lower portion thereof can swing outwardly for the discharge of thematerial, andalso en; abling, thedoor to be "raisedand swungout of theway when not in use. r

The invention also has for an object the improvement ofthe'construjction to enhance the utility and efliciency of the door. 7

With the foregoing and other objects in view, which. will beapparent 'asthe descrip tion proceeds, the invention resides in the construction andarrangement ofpartgas hereinafter described'an'd claimed, it beingunderstood that changes can be madewith in the scope ofwhat is claimed,without departing from the spirit of the invention.

The invention is illustrated in theaccompanying drawings, wherein-Figure '1 is a face'vi'ew of the door.

Fig. '2 is a vertical section on the line 22 of Fig. l. v

F'g. 3 is a vertical section on the same line show'ing'the door'sections raised and swung inwardly. i

Fig. 5 is an enlarged section 'on'the line 5-5 of Fig. 1. V r

The door frame of the car wall has the posts 7 and 8 and the sill 9, andthe door is 'colnposed of the lower and upper sections 10 and -1*1-,1=es' e ctive1 The lower section 10 is of greater height "than the uppersection, andisa'id sections 'a're' o'f a size to fit'sn'ngly withinthefol'oor opening with the upper section restingon the-flowero'ne, forretain preferably The bars i2 have the thereof and havetrt'innionsorpi'vot studs 17 projecting tronithe v'ertical edges of the doorsectionsand extending within the slots 15, for guiding the door sectionstorjup and down-movement "and permitting said sections to swiiiginwardly and outwardly about the'hori'zo11tal;aXes of "said trunnions.

Channetbinding, members 18 "are preferably secnred-"onth'e' vertical"edgesot the 'door 1 sections, gmdt'he plates-16 extend across saidmembers. The door "posts arefa'l'so preferably formed with grooves 19behind the slots 15 for receiving the 'trunnions 17. The "bars 12 extendtro'rnthe lint'el of the door frame to a f point between i the ends ofthe posts, inasmuchas'said bars'need not extendbnt a slight'di'stancebelow the trunnions 17 "otthe lower jdoor' section 10. forder-to"taste/n .tliejdoor sections in closed position, latch bolts 20are slidable in" barrels'2'1' secured to theonter sidesot thedooisections adjacent to the end edges thereof, toenter holes in the-doorposts T whe'ntthe door sections are in position, as seen -in 'Figs. 1-and-f2.v The latch bolts 20 have finger pieces 22 forconvenientlyslid-vingsaidb'oltsand holding "them in either position.

"The lower 'door section has additionallatching nieanstor convenience inreleasing the lower se ctio n or portion of the door to startthe"discharge of the material. Thus, latch "b'o1ts 23" are slidable inbarrels or guides 24Psecure'd to the outer side of the, doorsectionx10atthe vertical edges thereof, to enter holes or sockets in the door posts,

' sections from the hooks.

and the bolts 23, are connected by links 25 with a hand lever 26disposed between the vertical edges of the door on the outer sidethereof. The links 25 have rows of apertures 27 for the engagement ofthe pivots 28 which connect said links and lever, to provide foradjustments, and enabling the latching device to be applied to doors ofdifferent widths. The lever 26 is fulcrumed on a stud 29 of a fulcrummember 30 having a base flange 31 secured to the door section 10, as at32, and a bolt 33'eXtends through said door section and member 30 forclamping the intermediate portion of a bar 34 against the stud 29, tohold the lever thereon. The

bar 34 is bent in the form of a bow and has its ends secured, as at 35,to the door section 10 at the opposite sides of the member 30. The bar34 forms a guard and brace for the lever 26 and member 30, and alsoretains said lever on said member; A segment bar 36 is secured at itsends, as at 37, to the door section 10 and the upper handle end of thelever 26 projects upwardly behind said bar for retaining said lever inplace. The bar has a series of apertures 38 for receiving a pin or key39 used in holding the lever 26 in position. The pin or key 39 ispreferably connected loosely to the lever 26 by a chain 40 to preventthe loss of said key or pin. This enables the lever 26 to be secured orlocked, for holding the latch bolts 23 in projected position.

The door section 10 is provided at its outer side with suitable handholds 41 for convenience in raisingsaid door section.

Stops 42 are secured to the posts 7 and 8 for limiting the outwardswinging movement of the door section 10 when it is swung open instarting the discharge of the material. I

U-shaped members or keepers 43 are secured to the outer side of the doorsections adjacent to the lower edges thereof, for the engagement ofsuspension hooks 44 pivoted to a rafter 45 or other overhead support inthe car, thereby enabling the door sections to be supported in raisedinwardly-swung position, as seen'in Fig. 3. The bills of the hooks areengageable in the members 43, to prevent accidental disconnection of thedoor The bars 12 have notches 46 neartheir upper ends extending from theslots 15 for receiving the trunnions 17 when the door sections areraised, to thereby support said door sections in connection with thehooks 44.

In using the door, the sections thereof are lowered into position andthe latch bolts 20 and 23 are projected into the holes in the doorposts, for holding the door firmly in place, and the material can be runinto the car over the door, there being an opening above the door forthat purpose. After the car is filled, the ordinary outer door (notshown) can be closed and sealed, and such outer door is opened prior tothe opening of the inner grain door. To start the discharge of thematerial, the latch bolts 20 of the lower door section are firstreleased, and the pin or key 39 is disengaged from the lever 26. Then,by swinging said lever, the latch bolts 23 can be simultaneouslyretracted from the door posts, thereby releasing the lower door section,and the-pressure of the material against same from the inside will swingsaid door section outwardly,

thereby starting the discharge of the material over the sill 9. Thestops 42 will limit the outwardly swinging movement of said doorsection, to prevent injury to the operator, as well as restricting theflow of material. lieved of pressure from the material within the car,said door sections canbe raised and moved out of the way. The latchbolts 20 of the upper door section 11 are first released from the doorposts, and the section 11 is slid upwardly and its trunnions 17 movedinto the upper notches 46. The door section 11 is then swung inwardlyand upwardly and engaged by the corresponding hook 44.

After the door sections are re- The lower door section 10 is thensimilarly raised and its trunnions 17 moved into the lower notches 46,after which the door section 10 1s swung inwardly and upwardly andengaged by the other hook 44. The door, sections are thus supportedoverhead until i again needed.

Having thus described the invention, what is claimed as new is a A doorconstruction comprising a door frame having posts, said posts havingsubstantially vertical slots in their adjacent sldes between their outerand lnner sides, upper and lower door sectlons to seat one on the other,saiddoor sections being disposed between said posts with their ends inabuttingrelation with the adjacent sides of said posts, trunnionsprojecting from the vertical edges of each door section below the upperedge thereof and working in said slots, said door sections, whenreleased, being slidable' name to this specification in the presence oftwo subscribing witnesses.
